Linear Functions Preserving Sut-Majorization on RN
Suppose $textbf{M}_{n}$ is the vector space of all $n$-by-$n$ real matrices, and let $mathbb{R}^{n}$ be the set of all $n$-by-$1$ real vectors. A matrix $Rin textbf{M}_{n}$ is said to be $textit{row substochastic}$ if it has nonnegative entries and each row sum is at most $1$. For $x$, $y in mathbb{R}^{n}$, it is said that $x$ is $textit{sut-majorized}$ by $y$ (denoted by $ xprec_{sut} y$) if t...
متن کاملRecovering Baire One Functions on Ultrametric Spaces
We find a characterization of those Polish ultrametric spaces on which each Baire one function is first return recoverable. The notion of pseudo-convergence originating in the theory of valuation fields plays a crucial role in the characterization.
متن کاملOn Regularity-Preserving Functions
1 Some Homework Exercises In introductory automata theory, one can nd a wealth of entertaining automata-theoretic puzzles such as the classical rst halves problem: Show that if A is a regular set, then so is the set of all rst halves of strings in A: FirstHalves(A) = fx j 9y jyj = jxj and xy 2 Ag : Once students master the basic pebbling technique for solving such problems, they can move on to ...
متن کاملLinear Functions Preserving Multivariate and Directional Majorization
Let V and W be two real vector spaces and let &sim be a relation on both V and W. A linear function T : V → W is said to be a linear preserver (respectively strong linear preserver) of &sim if Tx &sim Ty whenever x &sim y (respectively Tx &sim Ty if and only if x &sim y). In this paper we characterize all linear functions T : M_{n,m} → M_{n,k} which preserve or strongly preserve multivariate an...
متن کاملOn Ultrametric Algorithmic Information
How best to quantify the information of an object, whether natural or artifact, is a problem of wide interest. A related problem is the computability of an object. We present practical examples of a new way to address this problem. By giving an appropriate representation to our objects, based on a hierarchical coding of information, we exemplify how it is remarkably easy to compute complex obje...
